I use Vim on windows (not gVim) because I think, that windows menu bar is ugly. So I use Vim, but I cannot fullscreen it. When I try it caps at cmd max size (1/4 size of screen) and won't be bigger.
Is there a way to either:
or
I believe that it's not Vim that you can't fullscreen: Vim in terminal mode runs in a terminal emulator. On Windows I think you can't make the console go full screen so this is absolutely not related to Vim.
However if you want to remove the menu bar from gVim you can read :h 'guioptions' and you'll find out that you can add this line to your .vimrc (or event better your .gvimrc) to do that:
set guioptions-=m
You can increase the size of any standard console window in Windows, including Vim.
In general, to widen the window, I adjust the Window Size Width. To make it less wide, I adjust the Screen Buffer Size Width. Editing in this way will prevent you from getting a horizontal scroll bar or having to edit both the values. For normal console apps I let the Screen Buffer Size be larger than the Window Size height to support scrolling vertically to see history, but that doesn’t apply to Vim, so you could use the same method above when changing the height.
The keyboard shortcut Alt+Enter can also be used to go into full-screen mode. This is also a standard Windows console feature, not Vim-specific.
For the gVim part of the answer, there are a few things you can add to your _vimrc. set guioptions -=m will remove the menu bar, and set guioptions -=T will remove the toolbar (below the menu bar). If you're not using these, you may wish to speed up load times by not building the menus: you can add let did_install_default_menus = 1 and let did_install_syntax_menu = 1 as well.
I know this is an old thread, but In windows terminal specifically there's padding by default making vim not the full size of the terminal. this can be changed In settings -> additional settings -> appearances: there's padding and a scrollbar visibility which can be disabled
